To all whom it vnay concern.-

.Be it known that I, SAMUEL JAcoBY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement inHermetically-Sealed Metal Boxes; and I hereby declare the following to be a full, clear,and exact description of the same.

My invention relates to improvements in hermetically-sealed metal boxes or tins which are adapted to contain biscuits, and which are thus sealed for the purpose of shipment by water or otherwise, and for other like containers.

It consists in the employment of a plurality of overlapping hermetically-sealing covers soldered to the top of the can and normally covered and protected by what is known as a slip cover, these sealingcovers being so disposed as to be successively removed for the purpose of obtaining access to the contents of the box.

Referring to the accompanying drawings, Figure 1 represents the box closed. Fig. 2 shows one of the cover-sections entirely and the other notremoved.

Tins for the shipment of various substances are made of the shape of the articles, and in the present case they are represented as rectangular boxes, as at A, adapted to receive similarly-shaped articles set on edge to till the 4 The body or bottom can from end to end. ends of the can may be made in any usual or suitable manner of tin or equivalent material, and the rip-covers 2 and 3 are preferably made of light tin, known as taggers tin. These covers are each fitted upon one end of the top of the can with the outline of which .they conform, and they are soldered in place so that they overlap approximately at the central portion of the'can, the rectangular portions of each cover being long enough so that one just overlaps the other. The two covers may be then tapered, as shown at i, and terminate in a folded slip having rings 5 attached. The inner cover. lies approximately flat, with this convergent portion and the ring lying beneath the convergent portion of the outer cover, which overlaps and is soldered to it. The inner cover has a depression, as at 7, stamped in it to register with the position of the ring of the outer cover, so that when the two-are in position, the ring of the outer cover is practically em bedded in the inner cover and substantially flush therewith. This allows the outer or slip cover 8 to be fitted upon the top of the box and above the two overlapping sections 2 and 3, and in this condition the box is ready for shipment. The convergent tongue of the outer cover is left free from the parallel straight edges to its apex where the ring is attached, and it may thus be turned up so that a good hold upon the ring may be obtained for the purpose of tearing the cover off when desired, the convergent tongue of the inner cover being thus left free and can be in the same manner upturned and serve for removing that cover. It will be understood that articles thus shipped can be preserved for any length of time in any climate or for sea use or for other purposes where they might otherwise become deteriorated and in such quantities that whenever a box is opened the contents can be used before deterioration takes place.

It is one object of this invention to enable the user to partially or entirely open thetop of the box. Thus when it is desired to open the box the outermost of the overlapping covers can be ripped or torn away by grasping the ring, leaving one end of the box open and its contents exposed; The other cover can in the same way be removed, thus exposing the whole interior of the box, so that convenient access can be had to the contents thereof. These inner covers having thus been removed, the outer or slip cover 8 can be placed upon the box and the contents thereof retained in good condition until they are used.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. A containing-box consisting of a metal body, a plurality of covers extending from opposite ends of theloody and having their inner ends overlapping, each of said covers S01- dered to the body and having an end extension -unattached to the body and provided with finger-engaging extremities by which the covers may be ripped from the body successively and in opposite directions.

2. A containing device consisting of a metallic box, a cover soldered across one end and along the sides to the center, said cover having a convergent or central tongue and a ring upon its free end, said tongue unattached to said body, a second cover soldered upon the opposite end and sides to the junction with the firstcover having a convergent tongue and ring, the inner portion of the outer cover being also soldered along the convergent tongue of the inner cover to hermetically seal the box and having the outer convergent portion left free whereby it may be upturned by a pull upon the ring to remove the outer cover, and an outer slip-cover inclosing the rip-covers and forming the cover of the box when the rip-covers are removed.

3'. A containing device consisting of a rectangular metal box, a plurality of covers soldered to the top of the box from one end to the center and also across their overlapping portions to seal the box, convergent tongues having rings to form a hold for the removal of each cover successively, the tongue of the outer cover being left free, a depression in the inner cover in which said ring is embedded, and a supplemental slip-cover adapted to fit upon the top of the box.

In witness whereof I have hereunto set my hand.

SAMUEL J ACOBY.
